Mechanism to create enterotomy between one or more compression devices

Abstract

The invention provides systems, devices, and methods for the delivery, deployment, and positioning of magnetic compression devices at a desired site so as to improve the accuracy of anastomoses creation between tissues, organs, or the like.

What is claimed is: 
     
         1 . An apparatus for placement of a compression anastomosis device, the apparatus comprising:
 a delivery device having a distal end and a proximal end,
 wherein one or more compression anastomosis devices are deployable from the distal end; and 
   an expandable and contractible control member that is independently deployable from the distal end,
 wherein the control member is manipulable such that it aligns one or more compression anastomosis devices with a deployment channel. 
   
     
     
         2 . The apparatus of  claim 1 , wherein:
 the control member is expandable to a diameter greater than that of the deployment channel to dilate a created enterotomy, and   the control member is contractable to a diameter equal to or less than the deployment channel to be removed from the enterotomy.   
     
     
         3 . The apparatus of  claim 1 , wherein the control member is a basket. 
     
     
         4 . The apparatus of  claim 1 , wherein the control member is a balloon cuff 
     
     
         5 . The apparatus of  claim 1 , wherein the control member is a wire jaw. 
     
     
         6 . The apparatus of  claim 1 , wherein the control member is deployable between distal and proximal lumens to capture a formed enterotomy. 
     
     
         7 . The apparatus of  claim 1 , wherein the control member is deployable to the distal side of a distal anastomosis device so as to act as a backstop. 
     
     
         8 . The apparatus of  claim 1 , wherein a piercing device capable of cutting, dissecting, and/or dilating tissue to thereby create a deployment channel between two lumens is deployable from the distal end. 
     
     
         9 . The apparatus of  claim 8 , wherein the piercing device is a hot needle. 
     
     
         10 . The apparatus of  claim 8 , wherein the piercing device is a hot tip emitting monopolar energy. 
     
     
         11 . The apparatus of  claim 8 , wherein the piercing device is a coring needle. 
     
     
         12 . The apparatus of  claim 8 , wherein the piercing device is a corkscrew. 
     
     
         13 . A method for positioning compression anastomosis devices, the method comprising:
 deploying a first compression anastomosis device from a distal end of a delivery device into a proximal lumen;   positioning the anastomosis device against a tissue wall;   piercing the tissue wall to create an enterotomy between adjacent lumens;   deploying a second anastomosis device through the enterotomy into a distal lumen;   independently deploying an expandable and contractible control member into the enterotomy;   expanding the control member to dilate the enterotomy;   engaging the control member with the second anastomosis device;   manipulating the control member rotationally and laterally with the distal anastomosis device so as to align the two anastomosis devices;   bringing the anastomosis devices together so as to capture the enterotomy;   contracting the control member to a diameter equal to or less than that of the delivery device; and   retracting the control member into the delivery device.   
     
     
         14 . The method as described in  claim 13 , wherein the control member is deployed on the distal side of the distal anastomosis device as a backstop. 
     
     
         15 . The method as described in  claim 13 , wherein the control member is deployed between the anastomosis devices to capture the created enterotomy. 
     
     
         16 . The method as described in  claim 13 , wherein the control member is a basket. 
     
     
         17 . The method as described in  claim 13 , wherein the control member is a balloon cuff. 
     
     
         18 . The method as described in  claim 13 , wherein the control member is a wire jaw. 
     
     
         19 . An apparatus for placement of compression anastomosis devices, the apparatus comprising:
 a delivery device having a proximal end and a distal end, the distal end having capabilities to cut, dissect, or dilate tissue between adjacent lumens to create an enterotomy;   an expandable and contractible control member that is independently deployable from the distal end of the delivery device into the enterotomy to capture the enterotomy;   the control member being able to be expanded to a diameter greater than that of the enterotomy to dilate the enterotomy;   the control member being rotationally manipulable so as to engage with a distally deployed anastomosis device and align it with a proximal anastomosis device;   the control member being laterally manipulable so as to bring the distal anastomosis device toward the proximal anastomosis device and pair them;   the control member being contractable to a diameter equal to or less than that of the delivery device; and   the control member being retractable into the delivery device.   
     
     
         20 . The apparatus of  claim 19 , wherein the control member is a basket. 
     
     
         21 . The apparatus of  claim 19 , wherein the control member is a balloon cuff. 
     
     
         22 . The apparatus of  claim 19 , wherein the control member is a wire jaw. 
     
     
         23 . The apparatus of  claim 19 , wherein the control member is deployable to the distal side of a distal anastomosis device as a backstop.
